Here's a 2 star from a well known, highly acclaimed film that provides one of its memorable moments: http://www.imcdb.org/vehicle_3273-Cadillac-Coupe-deVille-1979.html (Layla by Eric Clapton plays as the camera pans up to show the two dead bodies inside)

Here's another one most people remember: http://www.imcdb.org/vehicle_21619-Morris-Commercial-LC5-1953.html (PS. thumbnail needs fixing)
